Beta1 Sagittarii

Sagittarius Constellation

Beta1 Sagittarii  

I chose the Sagittarius Constellation (The Centaur/Archer) as my first celestial body because it is my birth sign, as I was born in December. I am absolutely, annoyingly independent, thus, I identify with this star sign a lot.

This constellation was categorized by 2nd-century astronomer Ptolemy with 48 other constellations. It remains one of the 88 modern constellations. This constellation (nicknamed The Teapot for its shape) can be seen by the naked eye.
